limit((1+x/(n+sin(n)))**n,n,oo) doesn't work

I think returning Interval(-1,1) for sin(oo) combined with interval
arithmetic will solve this issue.

(8) still returns 1. As far as I can tell, the issue appears to be that
gruntz fails, and the heuristic tries 1**oo, which it takes as 1.

I agree. 1**oo is a classic indeterminate. It doesn't agree with Python
floats, which set 1**float('inf') to be 1.0, but I think that's fine.

I see IEEE 754 has been envoked as justification for 1**nan == 1. IEEE 754
is a floating-point standard. 1**nan seems reasonable for floats to

This is because SymPy Live uses future integer division and your session
wasn't. It's best to avoid integer/integer like that. Just use f = (1 +

The incorrect output in both (7) and (8) occur because of the default
integer division in Python 2. This causes the expression in the

Currently both (7) and (8) return incorrect answer.
For (7), even gruntz returns an incorrect value of 1.
For (8), gruntz raises a PoleError

FYI, the current result is 1:
